I beg you to differ.
Not only as mentioned above- running on 12V having solar makes lot of sense, but I used my old TC fridge in my Sprinter van conversion with no propane.
Van has 250 amp alternator, dual AC and 4-cylinder engine can idle using 1/4 gallon of diesel per hr.
So the idea is to use van engine as generator.
Beside, 12V element, depends on fridge takes 10-20 amp, so it can run 2-4 hr on single battery (good for lunch stops).
But bare in mind that 12V elements are having smaller output than other ways. Driving often in 120F, occasionally I switch on inverter and run fridge on 120V mode.
DOn't do it. Yes, electrically it will run off batteries. Yes, it will kill batteries and alternators fast.
I actually burned out an alternator (I think 130 amp) driving two days running high loads. It was a nightmare to get the old one off, and I ended up having to run the generator to power the vehicle battery to get home. fortunately I had a high powered battery charger that was connected to coach batteries that had a switch to "jump" the vehicle battery so no jerry-rigging necessary. Not an ideal drive situation.
Running the inverter to run the heating element is even less efficient.
Run it on shore power or run it on propane, not DC unless you have a big enough solar array to let the sun 100% power your electric needs, and then only during daylight. Save your batteries at all cost!
Propane is cheap, new batteries are not.
If you have a special situation, a 250 amp alternator made to run high loads, a diesel that can idle for long periods and sip fuel, then you don't need any advice on how to run your rig, the rest of us are talking about the average rig, and diesels that DO NOT like to idle for long periods of time (these are not class 8 truck engines). Don't base your decision on what a class 8 rig can do if you have a regular camper...
On removal:
If it is junk, then get it out, break it apart or however and whatever needed. Otherwise you will need to pull it out thru the window. It is not a big deal to remove the entire window and re-install. There are post on doing this, and learning as you go is fine too. Dont fear the reaper.
